我是python的新手并尝试使用networkx来计算图形的eigenvector_centrality
,这是一个像这样的file.csv:
erwr,dfas,3
rfrf,g2rf,5
fewe,fef2,2
前两列作为节点,第三列作为边的权重。
我运行以下代码来获取图表eigenvector_centrality
的结果:
python
import networkx as nx
G = nx.read_weighted_edgelist("file.csv", delimiter=",")
G.edges(data=True)
centrality = nx.eigenvector_centrality(G)
print(['%s %0.2f'%(node,centrality[node]) for node in centrality])
我想知道如何导出eigenvector_centrality
的结果,因为result.csv文件的格式如下:
erwr,0.42
rfrf,0.38
fewe,0.32
第一列作为节点,第二列作为其中心性?我正在使用ubuntu和python2.7
提前!
答案 0 :(得分:2)
In [1]: import networkx as nx
In [2]: edges = """erwr,dfas,3
rfrf,g2rf,5
fewe,fef2,2"""
In [3]: G = nx.parse_edgelist(edges.split('\n'),delimiter=',', data=(('weight',float),))
In [4]: centrality = nx.eigenvector_centrality(G)
In [5]: for node in centrality:
print("%s,%0.2f"%(node,centrality[node]))
...:
g2rf,0.71
dfas,0.00
fewe,0.00
rfrf,0.71
erwr,0.00
fef2,0.00
